The Nidavellim or dwarves are a race of squat humanoids from one of the nine worlds of Yggdrasil.
The Nidavellim were a proud race of metalsmiths and armors respected in the nine worlds.
The Nidavellim once dwelled in a separate world from Midgard, Earth. However when the age of the gods ended, their world was one of many destroyed, thus relocated to Earth as a sanctuary. The Nidavellim hid themselves in the world of man in plain sight, in Stockholm and in Copenhagen.
